BOTTLE-CLOSURE.

Specification of Letters Patent.

Application filed November 24, 1915. Serial No. 83,191.

To all whom it may concern:

Be it known that Ldorm L. DUNNOCK, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Bottle-Closures, of which the following is aspecification.

This invention relates to bottle closures characterized by a cap which is mounted over the mouth of the bottle, and the object of the present invention is to provide a cap of this kind having novel and improved means for locking the same in place on the bottle, arranged to securely hold the cap in place, and also to enable the cap to be readily applied and removed.

With the object stated inview, the invention consists in a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing, Figure 1 is an elevation of a fragment of a bottle showing the application of the invention; Fig. 2 is a vertical section of the cap in place on the bottle, and Fig. 3 is a horizontal section on the line 3 3 of Fig. 2.

Referring specifically to the drawing, 5 denotes the neck of a bottle 6, said neck having an external encircling shoulder 7.

The cap which is the subject matter of the present application for patent comprises a to 8 and a depending circumferential side wall 9. At the junction of the top and the side wall is an annular rib 10 which is roughened to provide a cilitate the application of the cap to the bottle, and its removal. At diametrically opposite points, the side wall 9 of the cap said means being constructed and finger hold to fa has internal beads for locking the cap in place on thebottle neck 5. Each head is formed by making parallel slits 11 in the wall 9, and bending the material between the slits inward as indicated at 12. The slits donot extend as far as the edge of the wall 9, leaving the material between the slits in the form of a spring tongue which is connected at its ends to the material forming the side wall 9, and separated at the sides from said material. by the slits. The bead is therefore given sufficient resiliency so that it may be snapped over the shoulder 7, whereby the cap is securely held in place.

The cap can be easily and cheaply manufactured, and it provides a simple and efiicient closure for the bottle. The cap also contains an ordinary sealing'disk l3.

I claim:

1. A bottle cap comprising a top and 2. depending circumferential side wall, said wall having spaced parallel vertical slits terminating inward of the lower edge of said wall, and the material between the slits having an inward bend to form an internal bead.

2. A bottle cap comprising a top and a depending circumferential side wall, said wall having spaced parallel vertical slits terminating inward of the lower edge of said wall, the material between the slits forming a spring tongue connected at its ends to the material of the side wall, and free of said material at its sides, and said tongue having an internal bead.

In testimony whereof I afiix my signature in presence of two witnesses.
